The Lowdown

Alright folks, Rusty here, looking at the next stretch for Kennebunk Beach. Gotta be straight with you – this forecast is a tough one. We’re looking at a long, long stretch of nothing but small, poor-condition surf. For the next week and a half, through Sunday the 21st, there is just nothing on the menu. We're talking knee to waist-high mush at best, with a messy southeast windswell and onshore breezes. It’s the kind of stuff that’ll have you staring at your board in the garage wondering why you bother.

There's a light at the end of the tunnel though. A new, longer-period swell tries to show up mid-week, but it’s still tiny and weak. The energy just isn't there. We get a couple of clean windows with offshore winds on the 22nd and 23rd, but the waves are still only ankle to knee-high. On the 23rd, the wind starts howling out of the northeast, and by Thursday the 24th, it’s blowing a strong 28 mph. At that point, with the wind so hard and surf this small, you’re better off looking at kites than paddle boards. It's a proper washing machine out there, clean but completely unsurfable.

Here's the one real glimmer in the whole 16 days. Things start to change on Friday the 25th. A fresh southeast swell moves in. Friday morning we're seeing 2ft, but the afternoon jumps up to 3ft with a period of 8 seconds, and the energy is finally starting to build – hitting a moderate 152. The wind is a cross-offshore from the north, so it should be clean. Then Saturday the 26th looks even better. The swell pushes to 3ft in the morning and 4ft in the afternoon, with longer 9-second periods and energy climbing to a solid 217. The wind is light, but it's onshore, so don't expect perfection. This is still the best bet of the entire forecast. The water temp is about average for this time of year, so no surprises there.

Looking into the final day of the forecast, Sunday the 27th, there's a promising pulse of energy. The swell is 4ft from the ESE with an 11-second period and the combined energy is a strong 448. But, and it’s a big but, the wind is a direct onshore from the southwest. This could get messy, but it's the biggest swell of the period. It’s a distant, promising prospect, but one we’ll have to keep an eye on.

So, if you're desperate, mark your calendar for the 25th and 26th. It’s not going to be epic, but it’s the only thing resembling a wave in the next two weeks. The rest of the time, maybe go for a skate or tune up your fins. It’s a barren run, but it won’t last forever.

Rusty, out.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
